Using Database Replication for Cloud Migrations


A cloud migration is when a company moves some or all of its data center capabilities into the cloud, usually to run on the cloud-based infrastructure provided by a cloud service provider. However, there are always risks and challenges with migrating systems and databases to new environments.

This is especially true for cloud migrations, which involve a new remote location and completely different paradigm for provisioning compute and storage resources.

Fortunately, database replication has emerged as a reliable way to mitigate the risks of business disruption and impact during migrations.

DBTA recently held a webinar with John O'Brien, principal advisor and CEO, Radiant Advisors, and Clay Jackson, senior sales engineer, Quest, who discussed cloud migration benefits and architecture guidelines for database replication technology.

Before even migrating to the cloud, companies have concerns that range from:

  • Determining performance on a new platform - How can you parallel test applications and databases with real workloads?
  • Ensuring application and database recovery - How do you minimize recovery from a migration issue?
  • Minimizing business disruption

Cloud migrations can be made easier with database replication, O’Brien said.

Database replication is software that creates a synchronized copy of a database without interfering and a mature technology proven in mission-critical databases, he explained. Replicating to the cloud allows for user load testing with a failover. Replicated database improve benchmarking and configuration optimization.

Companies can then migrate from database replication into a hybrid system.

Jackson recommended SharePlex to help companies utilize data replication to make it easier to migrate to the cloud.

SharePlex offers:

  • Risk-free migrations
  • Anywhere data
  • Offload reporting
  • Maximum availability
  • Better performance
  • Kick-start big data projects
